with the active card does the inactive card begin to forward packets
across the backplane.
The phases of the initialization processes and their approximate times are
shown in Table 25.
Using the LEDsto Monitor theInitializationProcess
There are two ways to monitor the phases of the initialization process. One
way is to use the LEDs on the control card. For phase 1, examine the M/S
LED in the System Status LEDs on the control card. It flashes amber while
the card initializes its management software and changes to solid green at
the completion of the phase. If the chassis has two control cards, the M/S
LED continues to flash amber on the inactive card until the card has
synchronized its database with the active control card.
To monitor phase 2, watch the SBx Status LEDs. There are twelve LEDs
(numbered 0 to 11), one for each slot. The LED for a slot flashes green
while the card initializes its management software and configures its
settings in accordance with the settings from the active control card. The
LED changes to solid green when the corresponding line card completes
the initialization process and begins forwarding traffic.
If there are two control cards, you can monitor phase 3 by viewing the M/S
LEDs on the control cards. The LED on the active control card turns solid
green when the card is finished initializing its management software. The
same LED on the inactive LED continues to flash amber until it has

2 The line cards reset, initialize their
management software, and receive their
configuration settings from the active
control card. At the completion of this
phase, the Ethernet line cards begin to
forward traffic from their ports and the active
control card forwards packets across the
backplane. If the chassis has two control
cards, the inactive card does not begin to
forward traffic across the backplane until the
completion of phase 3.

3 The inactive control card matches its
database and load files with the active
control card. After completing this phase,
the inactive card joins with the active card in
forwarding traffic across the backplane, to
provide the full 400Mbps of bandwidth.
